Hi and welcome to the community!

Please take a look into the application note AN2867 - Oscillator Design Guide for ST MCUs, which is important to understand how to choose a crystal, how to calculate the load capacitors and the recommendation for layout.

For the HSE you can look directly into section 4.2, for the layout please read section 7.
